A numerical study of the flow interference between two circular cylinders in tandem by scale-adaptive simulation model
(Isfahan University of Technology, 2020-12)
Unsteady simulations of the flow around two cylinders arranged in tandem are carried out using Scale-Adaptive Simulation (SAS) turbulence model for high subcritical Reynolds number (Re = 2 x 105). Three-dimensional simulations ...
Experimental investigation of flow-induced vibration on isolated and tandem circular cylinders fitted with strakes
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
The effect of varying the geometric parameters of helical strakes on vortex-induced vibration (VIV) is investigated in this paper. The degree of oscillation attenuation or even suppression is analysed for isolated circular ...
The role of wake stiffness on the wake-induced vibration of the downstream cylinder of a tandem pair
(Cambridge, 2014-02-12)
When a pair of tandem cylinders is immersed in a flow the downstream cylinder can
be excited into wake-induced vibrations (WIV) due to the interaction with vortices
coming from the upstream cylinder. Assi, Bearman & ...
Secondary instabilities in the flow around two circular cylinders in tandem
(CAMBRIDGE UNIV PRESS, 2010)
Direct stability analysis and numerical simulations have been employed to identify and characterize secondary instabilities in the wake of the flow around two identical circular cylinders in tandem arrangements. The ...
On the wake-induced vibration of tandem circular cylinders: the vortex interaction excitation mechanism
(CAMBRIDGE UNIV PRESS, 2010)
The mechanism of wake-induced vibrations (WIV) of a pair of cylinders in a tandem arrangement is investigated by experiments. A typical WIV response is characterized by a build-up of amplitude persisting to high reduced ...
Wake instability issues: From circular cylinders to stalled airfoils
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Some recent results regarding the global dynamical behaviour of the wake of circular cylinders and airfoils with massive separation are reviewed in this paper. In order to investigate the effect of interference, the ...
Possible states in the flow around two circular cylinders in tandem with separations in the vicinity of the drag inversion spacing
(AMER INST PHYSICS, 2010)
The possible states in the flow around two identical circular cylinders in tandem arrangements are investigated for configurations in the vicinity of the drag inversion separation. By means of numerical simulations, the ...
